What is ectropion? Ectropion is an abnormality of the eyelids in which the lower eyelid rolls outward or is everted. This causes the lower eyelids to appear droopy. Ectropion exposes the delicate conjunctival tissues that line the inner surface of the eyelids and cover the eyeball, causing drying of the tissues, resulting in conjunctivitis.
The term PRN is a shortened form of the Latin phrase pro re nata, which translates roughly as as the thing is needed.PRN, therefore, means a medication that should be taken only as needed. Pain medicines, sleeping pills, and cough medicines are common examples of PRN medicines.ost blood pressure medications are taken as a preventive method or for controlling the rise of blood pressure. In light of this, a pro re nata (PRN) order from your doctor or â¦ cardiologist is unlikely. However, if the medication is for controlling acute systems of blood pressure, it is usually used pro re nata.
